Abstract
The present invention relates to a method for generating mechanical waves within a viscoelastic medium (11) comprising a step of generating an acoustic radiation force (15) within the viscoelastic medium (11) by application of acoustic waves focussed on an interface (13) delimiting two zones (11, 14) having distinct acoustic properties.
Claims12
A method for generation of mechanical waves within a viscoelastic medium comprising a step for generating an acoustic radiation force within the viscoelastic medium coupled with an imaging step of the medium, the coupling being such that propagation of the mechanical waves generated in the medium is imaged, the step for generating being carried out by application of acoustic waves focussed on an interface delimiting two zones having distinct acoustic properties.
An artificial membrane having a composition and/or a thickness selected to minimise the acoustic impedance contrast while increasing the amplitude of the mechanical waves intended to be placed partially in contact with the surface of a viscoelastic medium and intended to enclose a medium known as coupling medium placed between a device for generation of acoustic waves and a viscoelastic medium to serve as interface during execution of a method according to one of the preceding claims.
